Someone who has devoted their entire consciousness and personality to a random form of capitalistic media. Commonly found amongst gamers, music listeners, celebrity worshipers, anime freaks, etc. Will not hesitate to bash the living shit out of anyone who doesn't like what they like with such callous and witty insults as "fag" "fAg" and "FAG."

A fanboy is any person who is the unthinking pawn of a major label/brand. A fanboy is just about the most annoying creature on earth, particularly in the heated debate of Mac vs. PC or in the realm of politics. They tend to be really irrational, and unwilling to look at both sides of the debate: repeating things by rote and being completely partisan. Also, the typical fanboy is totally uninformed and biased to a precedent, hence the repetition of rote sayings or facts/myths.
Mac fanboy says "Apple can do anything! Even make an edible iphone, if only to prove they can do anything!!!!"

PC fanboys says "PC for the win!"/"Mac's may crash less but their crashes are worse!"

both tend to be dumbasses

An individual who thinks that XBox, Star Wars, comic books, action figures, TV shows, and so on are life-or-death matters that require zealotry. Such behaviors go far beyond merely being a hobby or favorite pastime. These individuals feel that social skills are not required, and see no problem with becoming hysterical over meaningless issues. They often falsely believe that they are simply showing their "inner geek", as if their behaviors are charming and a source of enjoyable humor. They also often think they are clever, and that others "just don't get it". Fanboys frequently show the characteristics of an arrogant, pseudo-intellectual, going on for hours in a droning monologue.
"Dude, that guy on Lost last night got owned! Dude!"

"You are such a fanboy, dude!"

"Am not! YOU are the fanboy, dude!"
